Our results show that the distribution of refractory abundance variations (Δ[X/H]) has extended tails, with about 10%–30% of all stars displaying variations around 0.1 dex. These variations are comparable to the accretion of 2–5 M⊕ of planetary material into the convective zones of Sun-...

The formation of stars and planets is accompanied not only by the build-up of matter, namely accretion, but also by its expulsion in the form of highly supersonic jets that can stretch for several parsecs1,2. As accretion and jet activity are correlated and because young stars acquire most...
恒星和行星的关系如下：1.恒星是由炽热气体组成的，本身能发光的天体。行星是围绕恒星运行的，本身不发光的天体。恒星是由恒星本身的引力形成的，在大气层中有许多固定的发光点，而恒星则是由气体星云引起的引力崩溃而产生的，而气体星云则是由氢、氦和其它元素构成，当恒星的核心浓度达到一定的时候，氢...
